A CORPORATION OF KNEW JERSEY.

sHINeLn MACHINE.

Application filed February 19, 1921.

To all whom it may concern:

Be it known that I, HERBERT ABRAHAM, a

States, residing at the clty, county, and State of New York,'have invented certain new and useful Improvements in Shingle Machines, of which the following is a specification.

The invention relates to a machine for cutting shingle strips from a web of prepared roofing material. Shingle strips consist of a plurality of units, generally two or four, forming inte gral flat strips, such for example as disclosed in my Patent No. 1,326,899, of-January 6, 1920, which when laid in overlapping courses simulate the appearance of individual shingles.

According to my invention I provide a machine having a pair of rollers extending transversely of the web and between which the web passes. each roller carrying cuttingdies so arranged that the dies carried on either roller operate against surface portions of the other roller as cutting beds, and whereby at each revolution of therollers completed shingl strips of the desired dimensions and shape, and having cleanly cut edges, are cut lengthwise from the continuously moving web.

The invention consists in the novel arrangement of parts hereinafter described and illustrated in the accompanying drawings, in which,

' Figure 1, is a front view of the cutting rollers of my improved machine, and,

Fig. 2, is a view of one of the completed shingle strips formed by said rollers.

The machine has a pair of rollers 1 and 2, mounted one above the other and'between which the material to be operated upon passes. iach roller is formed with a series of enlarged zones 3 and intervening zones 4 so arranged that the zones 3 of either roller are positioned opposite to the zones 4 of the other roller whereby to serve as beds against which the cutting-dies, carried on the portions 4, operate.

Suitably secured to the portions. 4 of the upper roller 1 are a series of cutting-dies 5 which extend circumferentially of the roller and are so designed as to form the longitudinal edges of the strips. Similarly the portions 4: of the lower roller 2 are provided with straight edge knives or dies 6 which \ure 1. By referring to these be seen that at each revolution Serial No. 446,419.

extend in the direction strips of the desired lengths.

If desired the roller 1 may be provided, in addition to the cutting-dies 5, with suitable dies 7 for the purpose of forming slots or kerfs in one of the edges of the strip as shown.

The two rollers are geared together at 8 to rotate in unison and they are held in proper alignment with each other by means of the collars or flanges 9 disposed at the ends of the roller 1 and engaging the ends of the roller 2, or by any means.

The machine is designed to operate upon a continuously moving web of prepared roofing material of the character usually employed in manufacturing shingles or strips, and to cut said web, both longitudinally and transversely, into completed shingle strips at each revolution of the rollers. The enlarged portions 3 of each roller which intervene the cutting-dies carried on said rollers not only serve as beds for the cutting-dies of the other roller to operate upon but also assist in producing cleanly cut edgesbecause of the fact that they tend to slightly separate the strips, in the direction of the width of the web, while the strips are being out.

In Figure 2 of the drawings I have illustrated a completed shingle strip of the type formed by the cutting rollers shown in Figfigures it will of the rollers a plurality of such strips will be cut acrom the width dies 5 will form the edges a of the strips, the cutting-dies 6 will form the ends 6, and the dies 7 will cut or punch out the slots or kerfs c.

Various modifications in the details of construction herein described and illustrated may be made without departing from the scope of my invention.

What I claim is:

1. In a shingle machine, a pair of rolls each having alternating zones of different diameters respectively, each roll carrying cutting-dies circumferentiall ofthe zones of lesser diameter, the rolls ii with the zones of greater diameter of one in other suitable of the web, and that the cuttingeing arranged 1 alinement with the zones of lesser diameter with the zones of greater diameter of one in of the other. alinement with the zones of lesser diameter 2. In a shingle machine, a pair of rolls of the other, one of therolls having flanges 10 each having alternating zones of different 'at its end fitting over the ends of the other 5 diameters respectively, each roll carrying roll to keep the two in alinement.

cutting-dies circumferentially of the zones bf lesser diameter, the rolls being arranged HERBERT ABRAHAM.
